21" round tubes are very rugged and forgiving. Not to say you can't break them, you must use common sense but they are very tough in their cabinets.of
The trick here is not to remove all of the support ears with the tube as they will have to be aligned again and you cannot do this out of the bezel. You loosen all of the ears, undo the large "hose clamp" strap and remove it then you can remove the tube. You will save yourself considerable time by not removing the ears, just loosen them.
